DOOR-STOP.

Specification of Letters Patent.

Patented Aug. 23, 1910.

Application filed June 1, 1910. Serial No. 564,416.

To all whom it may concern:

Be it known that I, WILLARD C. KNAPP, citizen of the United States,residing at yoming, in the county of Wyoming and State of New York, haveinvented certain new and useful Improvements in Door- Stops, of whichthe following is a specification.

The present invention relates to certain new and useful improvements indoor stops, and has for its object to provide a simple and inexpensivedevice of this character which can be readily applied to a door orswinging closure and which will operate in an effective manner to retainthe door either in a partially or entirely open position.

The inventionfurther contemplates a device of this character which isyieldably mounted so as to be held in a firm engagement with the floorwithout danger of 1narring or injuring the same, even should the floorbe finished with a fine polish.

The invention further contemplates a door stop which when swung intoinoperative position will form a buffer to prevent the door from beingswung into contact with the wall or base-board.

With these and other objects in view, the invention consists in certaincombinations and arrangements of the parts as will more fully appear asthe description proceeds, the novel features thereof being pointed outin the appended claims.

For a full understanding of the invention, reference is to be had to thefollowing description and accompanying drawing, in which:

Figure 1 is a perspective view of a door stop constructed in accordancewith the invention. Fig. 2 is a side elevation of the same, the floorengaging member being swung upwardly into an inoperative position, andFig. 3 is a similar view with the floor engaging member swung downwardlyinto an operative position.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawing by the samereference characters.

Specifically describing the present embodiment of the invention, thenumeral 1 designates a door or other swinging closure to which theinvention is applied. Akeeper 2 is detachably secured to the swingingedge of the door at a point near the bottom thereof by means of somesuitable fastening members such as the screws 8. A'spring strip t whichis preferably curved into substantially the shape of a spiral has theouter end thereof received within the keeper 2 and clamped firmlyagainst the door by means of the keeper. The opposite end of the springstrip 4 is formed with a bearing within which the upper end of an arm 5is pivotally mounted, the opposite end of the said arm being formed witha shoe 6 which is constructed of some resilient material such as rubber.When swung downwardly into the position indicated in Fig. 3, this shoe 6has a frictional engagement with the fioor 7 and retains the dooragainst any. swinging movement. However, when the arm 5 is swungupwardly into the position indicated in Figs. 1 and 2, the shoe 6projects outwardly from the door and serves as a buffer to prevent thedoor from being swung into engagement with a wall or baseboard.

Rigid with the pivot-end of the arm 5 and in the present instanceintegral therewith, is a finger piece 8 which operates within a slot 9in the middle portion of the spiral spring 4:. The ends of the slot formstops to limit the swinging movement of the arm 5, and the slot isslightly contracted at 10 at points toward the ends thereof so as toengage the finger piece 8 and yieldingly retain the same at either limitof its movement. It will thus be obvious that by grasping the fingerpiece 8 and moving the same into the upper end of the slot 9, the arm 5will be swung into an inoperative position so as to operate inconnection with the shoe 6 to form a buffer, while when the finger pieceis swung downwardly into the lower end of the slot 9, the shoe 6 will bemoved into engagement with the floor 7 so as to hold the door againstany swinging mo vement. Owing to the resilient action of the spiralspring 4, the shoe 6 will be held in a firm engagement with the floorwithout danger of scratching or injuring the same, and by loosening thescrews 3, the spring 4 can be raised or lowered as may be required toproperly adjust the device.

Having thus described the invention, what I claim as new and desire tosecure by Letters Patent, is:

1. In a device of the character described, the combination of a swingingclosure, a spring strip, means for adjustably securing the spring stripto the swinging closure, and floor engaging means carried by the springstrip.

2. In a device of the character described, the combination of a swingingclosure, a spiral spring strip having one end thereof secured to theswinging closure, and floor engagingmeans carried by the opposite end ofthe spiral sprlng strip.

3. In a device of the character described, the combination of a swingingclosure, a spring strip having one end thereof secured to the swingingclosure, a swinging arm pivotally mounted upon the opposite end, of thespring strip, a floor engaging shoe carried by the swingmg arm, andmeans for moving the swinging arm into and out of operative position.

4:. In a device of the character described, the combination of aswinging closure, a spiral spring strip having one end thereof securedto the swinging closure, an arm pivotally mounted upon the opposite endof the spring strip, a fioor engaging shoe carried by the arm, and afinger piece rigid with the arm for moving the arm into and out ofoperative position.

5. In a device of the character described, the combination of a swingingclosure, a spiral spring having one end thereof secured to i theswinging closure, floor engaging means mounted upon the opposite end ofthe spiral spring, and a finger piece for moving the floor engagingmeans into and out of operative position, the said finger piece engagingan intermediate portion of the spiral spring for retaining the floorengaging means in either position.

6. In a device of the character described, the combination of a swingingclosure, a. spiral spring having one end thereof secured to the swingingclosure and provided with a slot, an arm )ivotally mounted upon theopposite end of the spiral spring, floor engaging means carried by thearm, and a finger piece rigid with the arm and operating within thebefore mentioned slot of the spring.

7. In a. device of the character described, the combination of aswinging closure, a spiral spring having one end thereof secured to theswinging closure and formed at an intermediate portion with a slot, thesaid slot being contracted toward opposite ends thereof, an armpivotally mounted upon the opposite end of the spiral spring, floorengaging means carried by the arm, and a finger piece rigid with the armand operating within the said slot, the contractedportions of the slotserving to retain the finger piece yieldingly at either end thereof.

In testimony whereof I alfix my signature in presence of two witnesses.
